Like i already say : if you put specific information in token attribute, like Name-Surname, then you can add an hidden equation question type with {TOKEN:ATTRIBUTE_1} and have Name-surname in the survey.

I guess I am not being very clear here... I just want to assign two attributes Location and Evaluator Type... No name or specific identifying attribute. I then would like the survey takers to take the survey using their tokens then in the results be able to group Results by one or both of the attributes.

I answer : it's not possible with an anonymous survey
You ask !: why it's not possible ?
I answer: Because you can use Name/Surname in your attribute
You answer : but, me , i don't use Name/Surname.

And my final answre is :
- LimeSurvey core can't allow you to use Token attribute in your anonymous survey , because you CAN put some personnal information in token atribute. If you want to use toen attribute in your survey : set it to not anonymous.
